Lasioglossum (Dialictus) deludens Gardner & Gibbs 2023, sp. nov.

Lasioglossum (Dialictus) deludens sp. nov. urn:lsid:zoobank.org:act: 657A63A6-BF79-4EF1-A2B3-F2BE12AC0E6D Figs 12–14, 76C, 78D, 102C Dialictus deludens (nomen nudum) – De Luca et al. 2019: 4879. Diagnosis Females of L. deludens sp. nov. have the tegula relatively small (barely reaching posterior margin of mesoscutum in dorsal view if at all), translucent yellow-orange, impunctate, and with inner posterior margin straight; mesoscutum punctures smaller and finer in comparison to mesepisternum punctures, dense (IS <1 PD) and becoming moderately sparse anteromedially and usually submedially (IS = 1–3 PD); mesoscutum usually becoming shiny posteriorly; metapostnotum shiny with strong anastomosing rugae; mesepisternum densely punctate (IS <1 PD) and usually shiny; paraocular area with dense tomentum; and metasoma black to brown (rarely somewhat reddish, but never bright red-orange). Females of L. deludens sp. nov. are most similar to those of L. profundum sp. nov., L. rufodeludens sp. nov., and some L. diabolicum sp. nov. Females of L. profundum have the tegula dark brown, mesoscutum punctures about as large and coarse as mesepisternum punctures, and mesepisternum imbricate. Females of L. rufodeludens have the mesoscutum and mesepisternum completely dull and metasoma red-orange. Females of L. diabolicum have the tegula with at least some punctures medially (may be difficult to see if the tegula is very pale yellow) and the mesoscutum punctures about as large and coarse as mesepisternum punctures. Males of L. deludens sp. nov. have the same characters as for females, in addition to the face completely covered with dense appressed tomentum extending above eye emargination but not reaching median ocellus. They are most similar to those of L. profundum sp. nov. and L. rufodeludens sp. nov. Males of L. profundum have the tegula dark brown and, in direct comparison, the mesosoma and metasoma punctures are larger and coarser. Males of L. rufodeludens sp. nov. have the mesoscutum mostly or entirely tessellate and slightly more densely punctate (IS = 1–2 PD) and face with dense tomentum not extending above eye emargination. An undescribed species unrelated to the L. gemmatum complex and occurring sympatrically with L. deludens sp. nov. is superficially similar in both sexes, but the tegula is small and ovoid and the propodeum lacks an oblique carina. Etymology The specific epithet ʻ deludens ʼ is the Latin present participle of ʻ deludo ʼ (deceive, dupe). It refers to this species’ frequent misidentification in the past. An appropriate translation would be the deceiving sweat bee. Material examined Holotype MEXICO – Sonora • ♀; 30 km E of Agua Prieta; 31.30972° N, 109.25417° W; 20Apr. 2005; R.L.
